Abstract:Intestinal tract is an important barrier against external pathogens and toxins. Intestinal epithelial cells（IECs） and their tight junctions（TJ） constitute the structural basis of intestinal barrier. In intestinal surgery, factors as intestinal related diseases, surgical procedures and ischemia-reperfusion injury will cause varying degrees of damage to intestinal barrier, resulting in increased postoperative complications and prolonged recovery time. With the continuous development of enhanced recovery after surgery（ERAS）, the protection of perioperative intestinal barrier function is becoming more and more important for the enhamced recovery of intestinal surgery.Thoracic epidural anesthesia（TEA） has a significant protective effect on intestinal barrier and is easy to implement, so it has attracted much attention in the enhanced recovery of intestinal surgery. Based on the concept of ERAS, this paper reviews the enhanced recovery strategies of perioperative intestinal surgery as follows.
